Title: Paper feeding device
Inventor: WATANABE HITOSHI
IPC: B65H1/18
Filed: 1994-03-08
Abstract: PURPOSE:To avoid the occurrence of a paper feeding jam and skew feed caused by the up-warp deformation of sheets so as to feed sheets always positively regardless of the kind of sheets, the shelf time of sheets on a paper feeding base, environmental temperature and humidity change by compensating the up-warp deformation of sheets into flat shape to deliver the sheets even when the sheets placed on the paper feeding base are deformed into up-warp shape by the change with the lapse of time. CONSTITUTION:In a paper feeding device taking out sheets P, placed on a paper feeding base 1, from the uppermost sheet by a feed roller 21, the paper feeding base 1 is divided into plural paper feeding bases in the orthogonal direction to the sheet takeout direction, and both side paper feeding bases B, C among the divided paper feeding bases A, B, C are formed into vertically adjustable paper feeding bases vertically displaceable in relation to the center paper feeding base A. It is so constituted that the vertically adjustable paper feeding bases B, C selectively take either one of a first height position of the same height as the center paper feeding base A and a second height position lower than the center paper feeding base A.

IPC: G01G23/00
Filed: 1984-02-29
Abstract: PURPOSE:To enabling the switching of the function of a scale body between the connection time and non-connection time of a remote keyboard by detecting the connection state of the remote keyboard. CONSTITUTION:An electrical signal from a load cell 12 is inputted into an I/O port 6 through an amplifier 13 and an A/D converter 14 to make a CPU3 take in the data. On the other hand, a display interface 8 is controlled with the CPU3 to output a display data on a display unit 5. In addition, a remote keyboard 2 is equipped with a keyboard 17 having various keys and a key signal from the keyboard 17 is outputted to a connector 18 for body connection. The CPU3 checks the level state of a pin for detecting connection of a connector 16 through an I/O port 7 to detect the non-contact state of the keyboard 2 when the level state is high while detecting the contact state thereof 2 while it is low. In the latter case, the read contents of the program from a ROM4 is changed to alter the function of a power source switch button, for instance. Thus, the function of the scale body can be changed by the connection of the keyboard 2.
